You are thinking of the Jews. The Lord Jesus Christ made atonement by His blood. Once and forever. Done. He is both High Priest AND He was our ransom sacrifice.
Hebrews 7:26-27 For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens; Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.
Hebrews 9:11-12 But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
I.e., No goat sacrifices for Christians. The blood sacrifice was made once and forever at Calvary.
He ascended on high, led captivity captive, and gave gifts to men...
Thanks. You said it better. One and done, as they say.
But the earlier blood sacrifices were commanded and instituted by God to teach the point that only a blood sacrifice is adequate. That in turn pointed to the ultimate once for all sacrifice by Christ. God is the same yesterday today and forever.
